To all whom t mag] `Concern.: l Be it known that I, ALPHONSE GUTTLY, a citizen of Switzerland, residing at lVisconsin Rapids, in the county of lVood and State of illisconsin. have invented new and useful Improvements in lVrenches, of which the following is a specification.

My present invention has reference to improvements in wrenches.

My object is to produce a quick acting wrench in which the slidable jaw, by a pressure of the thumb or the finger of the operator thereon may be brought out of engagement with the shank ofthe stationary jaw and rapidly moved toward or away from said jaw, said slidable jaw being also provided with a screw which engages with the teeth of the shank of the stationary jaw, whereby a minute `adjustment between the jaws may be obtained for accurately engaging an object therebetween.

A further object is to produce a wrench in which all of the parts constituting the same shall be of `a simple construction and shall be interchangeable as well as easily assembled either when arranging the elements to provide a complete wrench or when repairs are required in parts of the wrench.

The foregoing, and other objects which,t

will appear as the nature of the invention is better understood, may be accomplished by a construction, combination and operative association of parts, such as is disclosed by the drawings which accompany and which form part of this specification.

In the drawings Figure 1 is a side elevation of a wrench in accordance with this invention.

Figure'2 is a top plan view thereof.

Figure 3 is a-sectional view on the linek 3 3 of Figure 1.

Figure 4 isl a sectional view on the line Lt-Lit of Figure 1.

Figures 5 and 6 illustrate details.

The stationary jaw 1 of -my improved wrench is integrally formed withan angle shank 2, and the said shank may have its free end beveled to provide an instrument to engage in the kerfs of screws or for other purposes. Also, theshank, adjacent to its free end is preferably provided with an opening whereby the wrench may be-suspended from` a nail or the like when not in use. The sides lof rthe shank are grooved longitudinally, and one of the edges thereof is provided with curved or arcuate teeth-3 formed by depressing the said edge -of the'` shank. j l

The movable jaw includes a carriage 4 carrying a head or jaw 5 and freely movable 60y v` over the shank 2. The carriage, at the center thereof has its top and its sides reduced v ork provided with` grooves" 6 respectively, whilethe saidl shank is also provided withaslot or opening in a line with the said grooves and which enter the bore of the shank. This slot or opening is indicatedvby y -the numeral 7.

Received in the grooves or sides ofthe shanks are plates 8.` These plates are con'- 70 v nectedat one oftheir ends by reduced poreL tions 9', the saidl reduced portions being received in a slot orl opening 7 and being formed with bearing openings for a shaft 10 on which is journaled a screw 11, the said 75 screw designed to engage with the teeth of the shank 2.y The groove in the top or upper portion of the shank or carriage 4 is cen# trally provided withv a depression 12 in whichV is seated a yspring' 13; The plates 8 have their confronting sides, which are'disposed opposite the said groove, channeled` as at 4, and in thesefchannels or grooves 14 there is received the reduced edges or tongues 15v formed on a plate 16. The plate 16 con,- tacts with the spring, so that the spring exerts a pressure thereagainst, and moves the yoke provided by the plates 8 in a direction to bring the screw 11 to engage -with the teeth of the shank 2. 4The outer surface of the plate 16 is preferably rounded and is milled, as at 17, whereby the operator may. freely engage the`same to exert a downward pressure thereagainst to move the yoke to bring the screw out of engagement with the teeth of the shank to cause the carriage to be moved longitudinally in either direction with the drawings will fully set forth the .1@15k construction and advantages of the improvement so that further description is not considered necessary.

Having thus described the invention, what is claimed as new, is

A wrench including a j 11,0 aw having a toothed shank, a carriage slidable on the f outer ends, a screw mounted in the bottom of the yoke Within the notch in the carriage, a plate mounted in the channels of the arms and provided with a recess opposite that in the'top of the Carriage, and a coil spring 15 mounted between said plate and carriage having an end seated in each recess.

In testimony whereof I aiix my signature.
